More About This Resource...

This experiment uses colored ice cubes to demonstrate how temperature changes water density. Working together in small groups, students can complete the experiment in a single class period. The printable eight-page handout includes:

A series of inquiry-based questions to get students thinking about how and why water temperature changes along with depth.

Illustrated experiment directions.

A worksheet that helps students use the experiment results to gain a deeper understanding of buoyancy and density.
